SKATE.

Specification of Letters Patent.

Patented Mar. 15, 192L Application filed May 20, 1920. Serial No.3s2,77o.

To all w lw. 'it muy cancer 72,:

Be it known that I, CARL B. DnnvrrsoN, a citizen of the United States,residing at Somerville in the county ot' Middlesex and State oflVlaSsachusetts, have invented new and useful Improvements in Skates, ofwhich the following is a specification.

This invention relates to an ice skate which includes a one-piececasting, composed ofmetal, such as aluminum, or an alloy of whichaluminum forms a considerable part, said casting including a baseportion and upstanding 'oot supports integral therewith, as in the skatedisclosed by my Patent No. 1,115,790, dated November 3, 1914, the baseportion containing the upper edge portion ot' the steel skate runner. Inthe skate shown by said patent the base portion of the casting is castdirectly on the runner, the strength ot the bond between the baseportion and runner being dependent entirely on the strength of the castmetal base portion. v

One object of the present invention is to strengthen the cast metal baseportion and the bond or union between the latter and the runner.

Another object is to mininize the quantity ot' the metal required forthe casting, thus reducing expense and Weight.

To these and other related ends the in- \'ention consists in theimprovements which l will now proceed to describe and claim.

Of the accompanying drawings torming a part of this specification,- I

Figure 1 is a side elevation of a skate embodying the invention.

Fig. 2 is a longitudinal section, showing the casting and thereintorcing member partially completed.

Fig. 3 is a perspective view. showing the reinforcing member by itself.

Fig. 4 is a View similar to Fig. 2, showing the casting and reinforcing'member completed and ready tor application to the runner. v

Fig. 5 is a side View of the runner by itself.

Fig. 6 is a section on line 6-6 of Fig. 4.

Fig. 7 is a section on line 7-7 of Fig, 1.

The same reference characters indicate the same parts in all of thefigures.

In carrying out my invention, I form upon an elongated sheet-metalrunner-engaging member, which is substantially U- shaped in crosssection, a one-piece casting, which includes an elongated base portioncast upon said member, and upstanding foot-supporting standards integralwith the base portion, the reintorcing member 'orning a downwardlyopening groove in the base portion of the casting, and having exposededge portions projecting below the base portion. The structure whichincludes the reinforcing member and the casting is toi-med before itsapplication to the steel runner of the skate, the runner beingsubscquently inserted in the said groove and bonded to the exposed edgeportions of the reinforcing member.

ln the drawings, I have shown the reint'orcing member as made from asingle piece or blank of sheet metal, preferably steel, and relativelythin, said member being substantially U-shaped in cross section, andincluding a hollow neck portion 12 and spaced apart flanges 13,projecting downwardly from the neck, and forming the sides of arunner-receiving groove. I have shown the one-piece casting as includingan elongated base portion 14:, cast upon the reinforcing member andinterlocked with the neck 12 thereof, as shown by Fig. 7, and upstandinpfoot-supporting standards 16 integral with the base portion. i

In practice, the ends of the reinforcing ember are closed by heads orplugs 17, before the base portion 14 is cast on the reintorcing member,said heads being formed to exclude the molten metal from the interior ofthe reinforcing member. It will be understood that the reintorcingmember having the heads 17 is suitably applied to a mold, adapted toform the one-piece casting upon the reinforcing member in such mannerthat the edge portions of the fianges 13 project from the base portion14, as shown.

After the removal of the casting and reinforcing member from the mold,the portions of the casting which project from opposite ends of thereinforcing member are cut by any suitable instrumentality, to formslots 18, the metal removed including the lower portions of the plugs17, as 'may be seen by comparing Fig. 4 with Fig. 2. The slots 18receive the end portions of the runner 20. the bottoms 18 of said slotsforming faces which are seated directly on the end portions of the upperedge of the runner. fl

The structure which includes the reinforcing member and the casting,being completed, as shown' by Fig. 4, the runner 20 s 1nserted in thegroove formed by the flanges 13 and the Slots 18, and the upper edgeportion of the runner is then bonded to the exposed edge portions ofthe' fianges 13 by suitable means, such as rivets 21, or by electricspot welding, the material of the re1nforcing member being such as topermt the bonding of the reinforcing member with the steel runner byspot weldng.

It will be seen that the sheet metal reinforcing member enables theone-piece casting to be securely connected w1th th e runner, after thecompletion of the casting, so that there is no liability of softening orannealing the runner by heat.

The reinforcing member occupies a considerable portion of the interiorof the base 14 of the casting, so that the quantity of cast metal isreduced to the minimum, and the casting is made correspondingly light,without sacrificing strength. ln case the runner is Secured to thefianges 13 by rivets, it is feasible to replace either a broken runner,or a. broken casting, by removing the 'ivets and substituting a new partfor the broken one.

I claim:

1. A skate comprising an elongated sheet metal runner-engaging member,substantially U-shaped n cross section, a one-piece casting including anelongated base portion cast upon said member, and upstandingfootsupporting standards integral With the base portion, said memberforming a downwardly opening groove in the base portion, and lavingexposed edge portions projecting below the base portion, and a runnerinserted in said groove and bonded to said edge portions.

2. A skate comprising an elongated hollow sheet metal member,substantially U-shaped 1,371,eoa

in cross section, and including a hollow neck and spaced apart flangesprojecting downwardly from the neck and forming the sides of arunner-receiving groove, a one-piece casting including an elongated baseportion cast upon said member and interlocked with the said neck, andupstanding foot-supporting standards integral with'the base portion, thesaid fianges having exposed edge portions projecting below the baseportion, and a runner inserted in said groove and bonded to said edgeportions below the base portion.

3.-A skate comprising an elongated hollow sheet metal member,substantially U- shaped in cross section, and including a hollow neckand spaced apart flanges projecting downwardly from the neck and formingthe sides of a runner-receiving grooVe, a one-piece casting including anelongated base portion cast upon said member and interlocked with thesaid neck, and upstanding foot-supporting standards integral with thebase portion, the said fianges having exposed edge portions projectingbelow the base portion, and a runner inserted in said groove and bondedto said edge portions below the base portion, the metal of said castingbeing excluded from the interior of said member to reduce the quantityof cast metal.

l. A skate comprising an elongated sheet metal runner-engaging member,substantially U-shaped in cross section, a one-piece casting includingan elongated base portion cast upon said member, and upstandingfootsnpporting standards integral with the base portion, said memberforming a downwardly opening groove in the base portion, and havingexposed edge portions projecting below the base portion, and a runnerinserted in said groove and bonded to said edge portions, the said basebeing extended at its ends beyond the said reinforcing member, andprovided with faces seated directly 'on the end portions of the runner.

ln testimony whereof I have axed my signature. u
